초록

2,4-이니르로 염화벤젠과 p-톨루이딘, 아닐린 및 p-염화아닐린간의 반응속도론적인 연구를 메탄올-아세트니트릴 혼합용매에서 실시하였다. 알코올의 수소에 의한 특수용매화로 실험결과를 해석하였으며, 용매의 변화에 따라 반응메카니즘이 변함을 알았다.

Kinetic studies on the rates of reactions of 2, 4-dinitrochlorobenzene with p-toluidine, aniline and p-chloroaniline in $CH_3CH-CH_3OH$ binary solvent mixtures have been carried out. The experimental results have been explained in terms of the specific solvation by alcoholic hydrogen. It has been shown that the bond breaking step is rate determining in the solvent system studied and the energy barrier is getting low as the solvent changes from acetonitrile to methanol.
